Pharmacokinetics and Safety Comparison of Tiotropium Inhalation Powder Administered as the Bromide Salt From Hard Polyethylene Capsule Via the HandiHaler® 2 and Spiriva® HandiHaler® in Patients With Chronic Obstructive Pulmonary Disease (COPD)
- Conditions
- Pulmonary Disease, Chronic Obstructive
- Interventions
- Drug: Tiotropium medium doseDrug: Tiotropium low doseDrug: Spiriva® HandiHaler® high doseDrug: Placebo via the grey HandiHaler®Drug: Placebo via the blue HandiHaler®
- Registration Number
- NCT02242266
- Lead Sponsor
- Boehringer Ingelheim
- Brief Summary
The primary objective of this trial was to establish non-inferiority of lung function response to tiotropium 10 μg, formulated as inhalation powder in the polyethylene hard capsule and delivered via the HandiHaler® 2, compared to tiotropium 18 μg, formulated as inhalation powder in the hard gelatine capsule and delivered via the HandiHaler® (Spiriva®) following single dose inhalation in patients with COPD. A hard polyethylene (PE) capsule with half the strength (tiotropium 5 μg) was included to investigate a dose ordering effect.
The secondary objectives were to characterize the pharmacokinetics of tiotropium inhalation powder hard PE capsule (delivered via HandiHaler® 2) and tiotropium inhalation powder hard gelatine capsule (delivered via HandiHaler®) and to compare the safety of the two pharmaceutical formulations.

- 121
-
All patients must sign an informed consent consistent with International Conference on Harmonization Good Clinical Practice (ICH-GCP) guidelines and local legislations prior to any study-related procedures, which includes medication washout and restrictions
-
All patients must have a diagnosis of chronic obstructive pulmonary disease and must meet the following spirometric criteria:
Patients must have relatively stable* airway obstruction with a pre-dose FEV1 <= 60% of predicted normal and FEV1 <= 70% of FVC at Visits 1 and 2.
- * The randomization of patients with any respiratory infection or COPD exacerbation in the 6 weeks prior to the Screening Visit (Visit 1) or during the baseline period should be postponed. Patients may be randomized 6 weeks following recovery from the infection or exacerbation
-
At Visit 1, patients must demonstrate an improvement in FEV1 of >= 12% over the baseline FEV1 value 45 minutes after inhalation of 4 puffs of 20 µg ipratropium bromide (Atrovent® MDI)
-
Male or female patients 40 years of age or older
-
Patients must be current or ex-smokers with a smoking history of more than 10 pack-years (Patients who had never smoked cigarettes had to be excluded)
-
Patients must be able to perform technically acceptable pulmonary function tests during the study period as required in the protocol
-
Patients must be able to inhale medication in a competent manner from the HandiHaler® 2 and the HandiHaler® devices
- Patients with significant diseases other than COPD will be excluded. A significant disease is defined as a disease which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study
- Patients with a recent history (i.e., six months or less) of myocardial infarction
- Patients who have been hospitalized for heart failure (NYHA class III or IV) within the past year
- Patients with any unstable or life threatening cardiac arrhythmia or cardiac arrhythmia requiring intervention or a change in drug therapy within the past year
- Patients with malignancy for which the patient has undergone resection, radiation therapy or chemotherapy within the last five years. Patients with treated basal cell carcinoma are allowed
- Patients with a history of asthma, allergic rhinitis or atopy or who have a total blood eosinophil count ≥600/mm3. A repeat eosinophil count will not be conducted in these patients
- Patients with a history of life threatening pulmonary obstruction, or a history of cystic fibrosis or clinically evident bronchiectasis
- Patients with known active tuberculosis
- Patients with significant alcohol or drug abuse within the past two years
- Patients who have undergone thoracotomy with pulmonary resection. Patients with a history of thoracotomy for other reasons should be evaluated as per exclusion criterion No. 1
- Patients who have completed a pulmonary rehabilitation program in the six weeks prior to the Screening Visit (Visit 1) or patients who are currently in a pulmonary rehabilitation program that will not be maintained throughout the duration of the study
- Patients who regularly use daytime oxygen therapy for more than one hour per day and in the investigator's opinion will be unable to abstain from the use of oxygen therapy
- Patients who are being treated with antihistamines (H1 receptor antagonists), antileukotrienes or leukotriene receptor antagonists for asthma or excluded allergic conditions. See exclusion criterion No 6
- Patients who are being treated with cromolyn sodium or nedocromil sodium
- Patients using oral corticosteroid medication at unstable doses (i.e., less than six weeks on a stable dose) or at doses in excess of the equivalent of 10 mg of prednisone per day or 20 mg every other day
- Patients with known hypersensitivity to anticholinergic drugs, lactose or any other components of the inhalation capsule delivery system (Spiriva® HandiHaler®; tiotropium HandiHaler 2)
- Pregnant or nursing women or women of childbearing potential not using a medically approved means of contraception for the previous three months (i.e. oral contraceptives, intrauterine devices, diaphragm or subdermal implants, e.g.: Norplant®)
- Patients who have taken an investigational drug within one month or six half lives (whichever is greater) prior to Visit 1
- Patients who have been treated with oral beta-adrenergics within one month prior to Visit 1 or during the run-in period
- Patients who have been treated with theophylline preparations within one month prior to Visit 1 or during the run-in period
- Patients who have been treated with the long-acting anticholinergic tiotropium (Spiriva®) within one month prior to Visit 1 or during the run-in period
- Patients with any respiratory infections in the six weeks prior to the Screening Visit (Visit 1) or during the run-in period. In the case of a respiratory infection during the run-in period the latter may be extended up to six weeks
- Patients who are currently participating in another study23. The randomisation of patients with any respiratory infection or COPD exacerbation in the six weeks prior to the Screening Visit (Visit 1) or during the baseline period should be postponed. Patients may be randomised six weeks following recovery from the infection or exacerbation
